No, the writes that stalled were tiny, no more than about 80 characters
being added to the activity log.  The above statistics are for the
writes to file descriptors 1 and 2, stdout and stderr, which are
directed to the activity or shell logs.  I did not examine the writes to
X socket, instance data, or journal.
